[QUOTE="Flip57, post: 119332, member: 6939"] I had the same thing happen and it was a failed low pressure fuel pump that feeds the injector pump. I replaced the fuel pump and everything went back to normal. Much later I found a hole in the pump bulb that caused rough running when fuel tank was down to half. Check it out before you tear the engine down. Some options would be to check to make sure there is fuel coming out of the injector return line flowing back to the tank. Maybe put a gauge on the fuel line between the low pressure pump and the injector pump. I'm not sure what the pressure should be. Make sure the screen on the pump is clean and is not leaking. I put an inline fuel filter between the squeeze bulb and fuel pump to keep the screen clean. It could be something else but this is what I found on my unit. [/QUOTE]
